Cloud by name indicates something which is very huge and present over a large area. Going by the name, in technical field, Cloud is something which is virtual and provides services to end users in form of storage, hosting of apps or virtualizing any physical space. Now a days, Cloud computing is used by small as well as large organizations for data storage or providing customers with its advantages which are listed above.
Mainly, three types of Services come associated with Cloud which are: SaaS (Software as a Service) for allowing users to access other publically available clouds of large organizations for storing their data like: gmail, PaaS(Platform as a Service) for hosting of apps or software on Others public cloud ex: Google App Engine which hosts apps of users, IaaS (Infrastructure as a Service) for virtualizing any physical machine and availing it to customers to make them get feel of a real machine.
Cloud Storage
Cloud Storage means storage of data away from users local system and across the span of dedicated servers which are meant for this. At its earliest, CompuServe in 1983 offered its customers 128k of disk space which could be used to store files. Whereas this field is under active development and will be because of potential threats including: loss of data or information, data hacking or masquerading and other attacks, many organizations have come forward with their own solutions to Cloud Storage and Data Privacy which is strengthening and stabilizing its future.
In this article, we will present some of selected contributions for this concern which are open source and successfully being accepted by huge masses and big organizations.
1. OwnCloud
A Dropbox replacement for Linux users, giving many functionalities which are similar to that of DropBox, ownCloud is a self-hosted file sync and share server.

3. Pydio
Earlier known by the name AjaXplorer, Pydio is a freeware aiming to provide file hosting, sharing and syncing. As a project it was initiated in 2009 by Charles du jeu and since 2010, it is on all NAS equipment’s supplied by LaCie.
Pydio is written in PHP and JavaScript and available for Windows, Mac OS and Linux and additionally for iOS and Android also. With nearly 500,000 downloads on Sourceforge, and acceptance by companies like Red Hat and Oracle, Pydio is one of the very popular Cloud Storage Software in the market.
In itself, Pydio is just a core which runs on a web server and can be accessed through any browser. Its integrated WebDAV interface makes it ideal for online file management and SSL/TLS encryption makes transmission channels encrypted securing the data and ensuring its privacy. Other features which come with this software are: text editor with syntax highlighting, audio and video playback, integration of Amazon, S3, FTP or MySQL Databases, image editor, file or folder sharing even through public URL’s.
4. Ceph
Ceph was initially started by Sage Well for his doctoral dissertation, and in fall 2007 he continued on this project full time and expanded the development team. In April 2014 Red Hat brought its development in-house. Till now 8 releases of Ceph have been released latest being Hammer in April 7, 2015. Ceph is a distributed cluster written in C++ and Perl and highly scalable and freely available.
Data can be populated in Ceph as block device, a file or in form Object through RADOS gateway which can present support for Amazon S3 and Openstack Swift API’s. Apart from being secure in terms of data, Scalable and reliable, other features provided by Ceph are:
- network file system which aims for high performance and large data storage.
- compatibility to VM clients.
- allowance of partial/complete reads/ writes.
- object level mappings.
5. Syncany
Released in about an year ago in near March 2014, Syncany is one of the lightest and open source cloud storage and file sharing application. It is currently being actively developed by Philipp C. Heckel and as of today, is available as a command line tool for all supported platforms, but GUI version is under active development.
One of the most important feature about Syncany is that it is a tool and requires you to bring in your own storage, which can be FTP or SFTP storage, WebDAV or Samba Shares, Amazon S3 buckets etc.
Other features which make it an awesome tool to have are: 128-bit AES+Twofish/GCM encryption for all the data leaving the local machine, file sharing support with which you can share your files with your friends, offsite storage as chosen by user instead of provider-based storage, interval-based or on-demand backups, binary compatible file versioning, local deduplication of files. It can be more advantageous for companies who want to use their own storage space rather trusting some providers provided storage.
6. Cozy
Not just a file sharing or synchronization tool or software, Cozy is bundled as a complete package of functions that can help you build your complete App Engine.
Like Syncany, Cozy provides flexibility to user in terms of storage space. You can either use your own personal storage or trust Cozy team’s servers. It relies on some open source software’s for its complete functioning which are: CouchDB for Database storage and Whoosh for indexing. It is available for all platforms including smartphones.
Main features which make it a must to have Cloud storage software are: ability to store all the Contacts, Files, Calendar, etc in the Cloud and sync them between laptop and smartphone, provides ability to user to create his own apps and share them with other users by just sharing Git URL of the repository, hosting static websites or HTML5 video game consoles.
As a step further to provide its availability even for cheap hardware’s, Cozy team has introduced Cozy Light which performs well even on cheap hardware’s like: Rasberry Pi, small Digital Ocean VPS etc.
